Tweeters vented their anger on a variety of themes. Some of those who voted "leave" said they now felt betrayed and wish they could turn back time and opt to remain. Others called out those same "leave" voters for choosing to exit the EU without having done the proper research:

Multiple people have reportedly admitted they didn't actually understand what they'd been voting for, either believing they were registering a protest vote against the government or just presuming that the "leave" campaign would never win.

The campaign to leave won 51.9 percent of the vote in Thursday's referendum, compared to 48.1 percent on the "remain" side. It's prompted the resignation of Prime Minister David Cameron and sparked fears that other European nations could follow suit in leaving the union.
